Okay so after consulting with a couple breeders and forums, I decided to go with either of these for an outside enclosure:

I will try for the first one, as it is all metal (impervious to gnawing), looks to be strong enough to defeat even coyote attack, on rollers, doubt a rabbit will be able to shake or rattle it....and I don't see stoats or even snakes being able to squeeze through the slit-holes. The second one is Plan B.
I cannot keep a rabbit outside year around in Riverbank. Except for two or three months in the winter, the usual daytime temperature is in the mid-80s to 100F+ (my central air conditioning is a must), but the usual nighttime temperature does not exceed 65F, so that is within rabbit tolerance. I will be moving into a 'open-concept' studio, so I cannot keep a rabbit inside year around. Rabbits tend to nap, not sleep, and zoomies a couple times a night would not be acceptable, nor rattling the cage, or any other noise that can penetrate my silicone earplugs. I'm a very light sleeper, and once woken up I become insomniac. I also have a senior cat, and while he is scared witless of anything/everything possible to be scared of, supervision between cat and rabbit is still required.
Rabbits are not Einsteins. Simply by altering the time I put the rabbit outside, I should be able to prevent him from wising up...if not, a casting net should work as last resort. I live a very spartan lifestyle, so very little furniture and junk for evasive maneuvers or cover. This may well not be an ideal situation for a rabbit. Robin Leach may never want to interview him for 'Lifestyles of the Rich and Famous'. I would contend that it will be far better than life in a small cage at the SPCA, or being sold to someone with a bunch of screeching kids, or someone with a 'hopper-popper'. Me and Buddy will have to adapt to the rabbit, and the rabbit will likely have to adapt to us. It's a (gasp!) compromise situation, where the rabbit will have to get use to not being the 'alpha' of the colony.
